Meet Our Founder

Brett LeMaire

Brett’s path to arboriculture began in ecological science, studying forest systems and fire management in Yellowstone. In 2008, he founded Knothead to bring science-driven, honest tree care to Colorado communities. What started as one arborist with a saw and a science background has grown into a trusted Front Range team known for tackling Colorado’s toughest tree challenges. 

And through it all, Brett has stayed committed to one thing: delivering tree care that respects Colorado’s terrain, its climate, and the people who call it home.
